Eveeyrime I fly they are begging for bags due to cabin overhead space. What they should so ia take the bags that are clearly too big to fit wheels first on their side. And those of us who give up the bag should really get their bags first. When boarding, nobody wants stupid jokes about how hot it is on board. Give us some cool air. Im usually sick from the heat by the time we take off.

Friendly crew kept coming by to make sure all was ok, provide additional refreshments, etc.

SW can't get their wifi right. I upgrade to insure wifi service but the last two trips had intermittent service. Not worth the extra costs.

Kayak could’ve posted the correct gate number. Almost missed my flight.

Slow boarding, limited food and drink portions. Bad delays and turbulence

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

Truly terrible. Will never willingly fly southwest again. Seats are worse than before they switched to assigned seating. One flight attendant was the opposite of helpful (rude, unhelpful, dismissive, and as my stranger seatmate said unprompted: a total prick). This caused me, 15 minutes into the flight, to book an alternate return flight home on a competing airline (first class 1.2k purchase instead of my existing planned flight) just so I would not have to ever be on that aircraft, with that terrible service person, with those horrific seats ever again.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

The crew and everyone on board was wonderful, We had to wait for a flight attendant to come from Orlando to Jax after a sudden illness., We left an hour late and “missed “ our connection.flight. The plane was held for us but we were told that our bags probably wouldn’t make the flight even though we would and would have to return to the airport in Boston pick up our late luggage or choose to fly on the same flight as our luggage. We chose to wait 4 hours on the next flight with our luggage and missed our first day in Boston for our grand daughter’s 10th bday celebration. When we arrived on the next flight, our luggage was sitting in a room waiting on us - evidently it did make out original flight., We were given meal vouchers in Baltimore for our delay which we really appreciated and thought was a very kind gesture by Southwest - sudden illnesses are not their fault., I just feel like we would not have missed an entire day in Boston if you offered more early morning direct flights and /or had offered to deliver our luggage to the hotel instead of us having to return to the airport to retrieve our luggage on the next flight due to a technicality - it wasn't “lost luggage”. Other than that , it was a perfect flight .

Always dependable. No surprises. That’s how I like to fly!

Boarding was quick and i made my connection early due to early arrival time

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Aside from a completely packed plane, I really have no complaints.

The flight was very good and the staff was very friendly and helpful!

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The food is terrible. The staff is wonderful. Comfort is good.

Having to up charge for a seat assignment is not good. Delta can do better

Excellent check-in. Crew was good. Excellent communication from flight deck.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

Flight was on time, the staff was personable & professional, & the plane arrived on time.

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

Horrible experience. They delayed our flight 7 hours!! We had to seat at the airport with kids on 4th July all day!

Horrible I am at almost 2,000,000 miles on United. This was probably the worst flight ever. An hour and a half before takeoff I get a message that they’re changing the plane and I no longer have a seat in Polaris business Supposedly, there was a problem with the plane, but then there was no other plane Finally, they decided to bring a plane from Newark to Washington Dulles Of course the original flight was at 10:45 PM so by the time the plane got there it was 12:30 AM. It had not been cleaned. It had not been catered. They don’t really have people available to do those things when it’s not pre-programmed at 1 o’clock in the morning. The crew had to be changed And the new plane held 28 fewer people than the scheduled plane There is no way you can hate United Airlines enough The people at the gate were actually just fine, but it was management who was completely useless And did they send extra help to the people at the gate? Did they send supervisors? Of course not. Just don’t take United find somebody else or buy a boat

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

This is for UA2274 from Houston to Sacramento. The flight was delayed arriving due to mechanical issues so we left about 3 hours later than scheduled. When boarding the plane the temperature inside was excessive - likely close to 100. Pilot apologized and said it was going to improve at altitude, which it did. But before that I honestly thought there might have been more delays removing passengers made ill from the heat. We were delayed leaving due to another mechanical issue. There was not water on the plane due to a panel that was not secured. They did that quickly, but the combination of mechanical issues was rather disturbing and did not reflect well on United.

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

United domestic flight was better than international flight. There was no switch to control Ac In international united flight. Food was also average, Air canada food was much better than united.

They cancelled our flight at the last minute due to mechanical issues. Rather, they “delayed” it till the next morning. A pain in the neck when traveling with two young children. Crew was really nice, which made up for it somewhat. This is the second flight from delta that was cancelled this year. Definitely going to fly another airline when possible

Noticing spectacular about the flight. It got me fro m point a to b. High priced

Everything was done like clockwork and I find no fault with the airline.

Like all planes recently, entertainment is achieved by giving the patron free WiFi and letting them stream shows via the screen on a phone or tablet.

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

Delayed 4 hours from Charlotte to Nashville. Could have driven there faster. Information provided by AA was sparse.

Gate change was a little tough but it was a good flight otherwise

Great flight, great service but most of all- our luggage made the trip with us.,
